In mid-2011 Intel created the Ultrabook name and a set of standards for this subset of Windows notebooks. The 13" MacBook Air is the obvious reference design for the Ultrabook: a 3 lb., extremely thin yet fairly powerful portable with a 13.3" display. Since Intel came up with the platform, the requirements include Intel Core i3, i5 and i7 Sandy Bridge second generation CPUs and chipsets (and Ivy Bridge third generation CPUs when available in the second half of 2012). Intel wants these machines to use Intel integrated graphics, Intel WiFi and Bluetooth and have SSD drives. Intel WiDi is a part of the package (though not required). The cosmetics, display resolution and type as well as ports are up to the manufacturer, and most make upscale machines to compete with the Air. Intel's target price is $1000, which undercuts Apple's MacBook Air by several hundred dollars. These notebooks are capable enough to be primary machines for business and school, but they're not a great fit for lots of HD video editing and demanding 3D gaming.
